Denae D.-
This lesson is about formulas and equations and how to use them with math. formula is using a no equal sign in it. And and equation has and equal sign in the problem.
Ashley U.-
This lesson is about equations and formulas.
Equation- a statement in which two numbers or expressions are equal. True Equation- Both sides of an equations have the same numerical expression. False Equation- Numerical expressions on both sides of an equation are not equal . Open Sentence- an equation that contains one or more variables. Solution of the equation- find all the value of the variable that make and equation true. Formula- an equation stating a relationship between two or more quantities.
Students Summaries:
Basically the way you solve equations is to do the opposite. If your adding you subtract and if your multiplying you divide. The easiest way I found was to just look at the numbers and ignore the variable so you don't get mixed up. And on fractions you can solve by using the reciprocal. Hayden
Allison- This lesson uses two properties, the addition property of equality and the multiplication property of equality. These help to perform one step equations. By isolating the variable, you do the same to one side of an equation as the other.
Student Summaries: In 3-4 we discussed how to solve two step equations. Two step equations are equations that take two steps to solve. You have to get the variable by itself. Also you use opposite operations like we did in one step equations. - Abi M.
Student Summaries:
A proportion is an equation where two ratios are the same. A proportion an be written in words, colons and in fractions. To solve a proportion you would cross multiply. (then plug the answer you got back to check it) Olivia
A proportion is a equation stating the ratios are equivalent. proportions may be written in three different ways. the numbers of a proportions are called terms.
the three different ways you can write proportions are writing them as fractions also using ratios with colons and lastly by writing them in words with numbers. ( Charles G. )
Student Summaries:
in order to graph inequalities on a number line you need to no the different types of inequality signs. There is 2 signs which people get mixed up there is this one < which is less than and there is this one > which is greater than. there is also equal to, greater than and equal,and less than and equal to if it is 1 of those three you fill in the circle on the number line because it is a solution but if it is not you leave the circle open because it is not a solution. - Brandy C.
Section 3-6 deals with the concept of graphing inequalities on a number line. When solving these problems you will need a ruler and a pencil. The sings for graphing these are < less then, > greater then, ≤ less then or equal to, ≥ greater then or equal to, and ≠ not equal to. These symbols define how the problems will be graphed. An example of a problem would be A < 6 you would then graph this. When the inequality has a < or > sign the circle is open followed by a shaded line. When the symbol is ≥ or ≤ then the circle is closed followed by a thick shaded line. If you follow these steps you should have no troubles with this lesson. When solving an equation just solve for the variable to find the inequality. Andrew J.
Student Summaries:
In order to solve and inequality you must seperate the variable from the other numbers for example in the problem 2x+3=15 you must subtract the 3 to get the variable seperate then the problem would be 2x=12 after you subtract 3 from both sides. then you divide both sides by 2 to get the answer of 6 equaling x
